Gap, roller gap, roller convexity

If two object edges are joined together, a gap always remains. If the gap has to satisfy technical or visual requirements, the course with respect to the size must be checked. If the gap should be measured completely, laser scanners in the scanCONTROL series are ideally suitable for this. Point laser sensors in the optoNCDT group are also used for precise gap measurement over a track.

Monitoring tool deformation using inductive sensors based on eddy current enables high product quality combined with improved tool life and reduced rework. Usually, three to four eddyNCDT 3005 eddy current ...

So far, gap measurements inside the pumps were not possible because of the extreme requirements. The sensors must be resistant to high speeds, high pressures up to 1,000 bar and temperatures above 100 ...

To date, bearing gaps were measured during standstill based on a tactile principle. Therefore, long inspection intervals were required, which in turn, may increase the risk of a complete plant failure. ...

In high quality vehicles, the trim typically consists not only of a single material (e.g. plastics) but many different bonded materials. This offers various design options but also many additional functions ...

In the production of drinking glasses, the stem and cup are connected using a gas burner. In order to enable the precise connection of the glass stem and cup, the distance between stem and cup needs to ...

Hydrostatic bearings are used in large plant and machinery such as stone mills, telescopic installations etc. Monitoring the gap size is a critical factor, as any disturbances in the hydraulics can cause ...

In order to inspect the behavior of turbochargers during different stress states, eddy current displacement sensors are applied in turbocharger test benches. The miniature design of the sensors and their ...

The lubricating gap of a plain bearing is influenced by several factors such as temperature, speed, angle, load etc. This influence can only be measured under operating conditions.
Therefore, a measurement ...

Glass substrates are required for certain medical tests. During manufacture of silicon chips, the substrate is milled in a defined grid with a depth of 800µm. For separation, the substrate is broken at ...

To improve the construction of internal combustion engines and damage analyzes, it is neccessary to measure the thermal and mechanical loads in the engine. Two important variables here are the transverse ...

Rotary crushers for quarries or ore mines can grind up to 3500 t of material to the desired grain size in one hour. For this purpose an eccentric bearing bush generates a rotary-oscillating movement of ...

For continuous, uniform material processing in the field of sealing technology, the gap between the rolls must be set with the hydraulic adjustment device and maintained constant. For this reason the top ...

Included in the objectives of current engine development are minimization of pollutants and the reduction of oil consumption. In order to be able to take measures in achieving these objectives, then along ...

Eddy current sensors from Micro-Epsilon are used for various measurement tasks in tribology testers of the ITR in Clausthal. They withstand the harshest ambient conditions there as they measure directly ...

Among other things, the lateral movement of the piston in the cylinder is crucial for the service life of engines. Miniature eddy current sensors for this are integrated in the piston which measure onto ...

The Top Dead Center of the cylinder movement is measured for adjustment of the precise ignition point in engine development. In doing so, a miniature eddy current sensor is integrated in the cylinder head ...

Combustion engines must withstand maximum loads during a long service life. In order to deal with this requirement, eddy current sensors from the eddyNCDT series are installed in the engine for many different ...

The distance of both rollers from each other or from the roller to the support surface is the crucial dimension for rolling processes for metals, plastics or other materials. In the case of sensitive processes ...

Specially shaped eddy current sensors are integrated directly in the crankcase where they measure, for example, the expansion of the cylinder head gasket during the stroke. Pressures of up to 50 bar are ...
